To all whom it may concern.

Be it known that I, FRANKLIN W. FRAMP- 'roN, a citizen of the United States, residing at Pomeroy, in the county of Gar field and State of Washington, have invented certain new and usefulImprovements in Boat-Hulls and Ballast Means Therefor;

and -I do hereby declarethe following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the'letters This invention relates to new and useful and figures of reference marked thereon,

Figure -lis-a ottom plan view of a boat made in accordance with my invention. ig.'2 is 'anend view, and Fig. 1s a cross ofthe drawings by, letter,-'-A- designates the hull of a. boat having two parallel keels B which are spaced, apart, as shown clearly inithe sectional view of the drawings, with ribs orbraces K are fastened to the opp plastic'state 'to parallel keel plastic condition with the upper surface of the concrete comin up flush with the tops ofthekeels and form ng a floor.

By theprovision of a boat having a hull with the double-keels as shown and spaced apart with concrete filling, a ballast is affordedWhich willfhold' the boat from tilting sidewise-and the keels, being spacedapart and parallel toeach other, form means for preventing the boat from drifting and cause the same to travel in a; true course.

What Iclaimto. be'new is:

A .boat having a hull with two parallel keels spaced apart and hollow, intersecting braces within each keel portion, ribs upon the innerfaces ofeach keel, a filling of concrete in which said braces and ribs are embedded, the'up'perfsurface of the concrete being continuous from one keel to the other. In testimony whereof I hereunto aflix my signaturein the-presence of two witnesses.
